Abstract

The first clinical use of homograft tissue in cardiovascular surgery was in 1948, when Gross used cadaveric arterial grafts to construct systemic to pulmonary artery shunts in patients with tetralogy of Fallot, and to repair coarctation of the aorta. Eighteen years later, a valved homograft was used for the first time in the treatment of congenital heart disease for reconstruction of the right ventricular outflow tract in a child with pulmonary atresia. Since these pioneering advances, valve and vascular homografts have become central to the management of congenital anomalies of the heart and great vessels. The primary use for homografts in congenital heart surgery today is establishment of a valved connection between the right ventricle and pulmonary arteries in children with tetralogy of Fallot with pulmonary atresia or other complicating factors, truncus arteriosus, transposition complexes, and double-outlet right ventricle, and in patients undergoing the Ross procedure. Homograft reconstruction of the left ventricular outflow tract has also been performed for many years in children with aortic insufficiency or recurrent aortic stenosis, but early homograft degeneration in young children has been a significant problem. Many surgeons are turning away from homografts in the systemic circulation in favor of the pulmonary autograft. Homograft is also widely used as a vascular patch material. In the present report, we discuss the various uses of homografts in congenital heart surgery, the benefits and drawbacks of homografts in young patients, and some of the future possibilities for homograft development and application in patients with congenital heart disease.
